⚠ Safety & Installation Notice
EARTHING CABLE - PROTECTIVE CONDUCT OR ONLY
This cable is specifically designed for earthing and protective conductor applications. It must ONLY
be used for grounding purposes and should never carry operational current. Always ensure proper
termination with approved earthing terminals and maintain continuity throughout the entire
grounding system. Regular inspection and testing of earth continuity is mandatory per local
electrical safety regulations.
